yes, this is normal Chaboum, 8 ° in Oko language it is when there is no need, and also when the boiler modulates downwards, its setpoint is 8 °
besides it annoyed me that it cuts the heating instead of sending less hot, because after it is hassle to go up ...
until I also deactivate the workshop probe - where I make a reduction - so that the regulator sends just less heat, according to the calculation of the curve (without compensation) - it was quite stupid, but I took a long time to find / understand ...
and even better: I always put in a reduction (14 °), the sun is enough to rise during the day (18 °), and I put back in my car only when it is gray and rain for several days.
and lately it was sunny and warm during the day, I stopped it outright: the sun was making me 20 ° and the insulation kept the night at 16-17 even when outside it dropped by 15-20 ° .
And there when it started to get cold and rainy again, it was still 16 ° inside (my day set point), but I was cold ... probably because the water in the walls was at 16 - so I re-lit, with setpoint 16 always, for this the boiler sent water at 20-22 ° in the walls - and suddenly it was good while the air was still at 16 ... confirming the theory that warmer walls that air = comfort (and vice versa ...)
This is what had convinced me, among other things, to opt for heated walls - and indeed I heat 3 ° less with that, and for much better comfort!
